django ajax jquery csrf_exempt 设置favicon.ico

• 响应ajax请求的views方法需要加上@csrf_exempt注解，否则post请求报错，get可以
• 设置favicon.ico，在url.py里加上path(‘favicon.ico’, RedirectView.as_view(url=r’media/favicon.ico’))即可

from django.contrib import admin

from django.conf import settings
from django.conf.urls.static import static
from django.views.generic.base import RedirectView

from django.urls import path
import app3.views as a3v

urlpatterns = [
    path('admin/', admin.site.urls),
    
    path('a3/ajax', a3v.ajax),

    path('favicon.ico', RedirectView.as_view(url=r'media/favicon.ico')), 
    # path('favicon.ico', RedirectView.as_view(url=r'static/img/1.jpg')), 

]
if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL,
                          document_root=settings.MEDIA_ROOT)

//app3\views.py
from django.short


cuts import render
from django.http import HttpResponse,JsonResponse
from django.shortcuts import redirect, render
from django.views.decorators.csrf import csrf_exempt

@csrf_exempt
def ajax(request):
    if request.method == 'GET':
        print(request.GET)
        return JsonResponse({'code':555,'method':'doget'})    
    print(request.POST)
    return JsonResponse({'code':666,'method':'dopost'})
